AUTOMOBILE LOCK.

Specification of Letters Patent.

Patented Apr. 11, 1922.

Application filed April 16, 1919. Serial No. 290,590.

ToaZZ whom it may con-cm:

. Be it known that I, VINCENT BoNozYK, a citizen of the United States of America, residing at Riverhead, county of Suffolk, and State of New York, have invented certain new and useful Improvements in Automo bile Locks, of which the following. isa speci iication.

This invention relates to improvements in looks and the principal object thereof is to provide a lock which is particularly adapted for use on motor vehicles.

' ,Another object of the invention is to provide a lock for controlling an electrical cir cuit. v

l/Vith these and other objects in View, as will appear as the description proceeds, the invention consists in the novel construction,

' combination and arrangement-of parts as set forth 1n the following specification,

claimed and illustrated in the accompanying drawings, in which Figure 1 is a face View of this improved lock.

Figure 2 is a sectional view through the device taken beneath the dial plate on line 2-2 of Figure 3. V

Figure 8 is a longitudinal sectional view through the device taken on line 33 of Fig. 1.

Figure 4: is a transverse sectional view of Fig. 2.

Figure 5 is a transverse sectional view taken on line 5-5 of Fig. 2.

Figure 6 is a sectional view on line 66 of Fig. 3, and

Figure 7 is a sectional view on line 77 of Fig. 5.

Referring more particularly to the drawings, the numeral 1 designates the casing or housing of the device having one open side which is adapted to be closed by a trans parent cover 2 secured in a removable frame 8, attached to the housing 1 by entering a recess 4 at one end, while the opposite end is held by a staple 5 through which a latch 6 engages.

This latch is formed on the reduced end 7 of a lever 8 which is pivotally mounted on the under side of the dial plate 10. This dial 1O is-secured in the housing 1 intermediate the rear wall and the cover, as clearly illustrated in the drawings. The inner end of the lever 8 extends well into the housing and aligns with an opening 11 in one side of the housing. A removable press button 12 is adapted to enter the opening 11 and engage the lever 8 so the same may be rocked on its pivot against the pressure of the spring 13 and thereby cause the latch 6 to be withdrawn from the staple 5 so the cover may be removed.

in order that the cover may not be removed by an unauthorized party, a gear 14 is'rotatably mounted bet-ween the apertured wall of the housing and the lever 8, and this gear is pierced as at 15, to'receivc the shank of the press button 12. A pinion 16 meshes with the gear 1 1 and is secured to a shaft 17 which is journalled in the apertured side wall of the housing and carries at its outer end a thumb piece 18.

The inner end of the shaft has attached thereto a bevel gear 19 meshing with a bevel gear 20 attached to a shaft 21 which is journalled in the dial plate and carries a hand 22 operating over the face of the dial 233, vhich is provided with characters thereon. It will thus be seen that upon rotation of the thumb piece 18, the gear 14 will turn and may be controlled so that the aperture 15 may be registered with the aperture in the side, to permit the plunger 12 to engage the lever 8 to release the latch.

Simultaneously with the rotation of the gear 14 the hand 22 will travel over the face of dial so that any one familiar with the relation of the hand and gear may readily the gear to proper position by observing the hand.

In order to further safeguard the device, an alarm controlling means is provided, which consists of a press button 24 hearing on a contact spring 25 attached to the inner side of. the dial plate and adapted to normally tend to engage a contact disc 27 carried on a shaft 28, the movements of which are controlled by the thumb piece 29.

The outer end of the shaft 28 carries a hand which operates over a dial 31 and a block of insulating material 32 is inserted in the disk 27 so that when positioned beneath the spring 25 no contact will be made regardless of whether or not the spring moves outwardly and against said disk. It will be noted that when the cover 2 is in position, the spring 25 will be held away from the disk, but as soon as the cover is removed the pressure on the button 241 will be released and unless the insulating block is directly beneath the spring 25 a contact will be formed which is capable of conducting electricity.

From the foregoing it will be noted that a person knowing the relation of the hand and the insulating block 32, may readily set the block beneath the spring 25 by operating the thumb piece 29 and observing the hand.

After the cover has been removed it will be evident that access may be had to thumb pieces 32 by which the movements of the disks 33 may be controlled. These disks 33 are mounted on spindles 3a which carry at their outer ends, in addition to the thumb pieces 32, the hands 35 which operate over the dials 36. The disks 33 are provided on their outer faces with insulating disks having recesses through which the contact lugs 36 extend." These lugs are formed integrally with the disks 33 and are adapted to engage the contact springs 37, as clearly shown in Figures 2 and 4.

Conducting springs 38 bear against the disks 83 and are connected to the spark circuit of the vehicle on which the device is used; thus it will be evident that after the cover has been removed, a person familiar with the relative posit-ions of the hands and the lugs 36 may readily turn the disks so as to form a complete electrical contact between the conducting springs 38 and thereby complete the spark circuit.

It will be understood that a suitable illuminating means 39 may be attached to the housing so as to enable a person to readily operate the device after dark and that the electrical source 40 may be used to operate an audible signal l1 as the bell shown.

From the foregoing it will be evident that a simple and efficient lock is provided wherein it is practically impossible for a person unfamiliar therewith to operate the same without detection.

While in the foregoing there has been shown and described the preferred form of this invention, it is to be understood that certain minor changes in the construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

hat is claimed is- A lock casing comprising a rectangular box having a recess in its inner wall adjacent the top edge at one end thereof, a cover having a part engageable in the recess, a staple depending from said cover, a latch p'ivotally mounted in said casing opposite the recess, said latch being engageable in said staple, a spring adapted to press said latch into engagement with said staple, a disc gear rotatably mounted adjacent said latch, said disc gear having an opening, a pinion meshing with said disc gear, means for actuating said pinion from the exterior of the casing, a press button pin slidable througlrthe wall of said casing when the opening in said disc gear is brought into register with the opening in said casing wall, and an extending pin on said button by which said latch may be released from said staple permitting removal of said cover.

In testimony whereof I have affixed my signature.
